Subject Hive backed with S3 EMRFS - Compactor Issues
Date Fri, 07 Dec 2018 20:36:31 GMT
Hello community,

We have hive setup on a separate EMR cluster with an external metastore on
an RDS. Tables are managed with S3 as EMRFs backing. We are using kerberos
as our user authentication for all edge nodes and machines on the cluster.

We are noticing that any changes from updates or merge statements to be
reversed when a major compaction is triggered (either manual or auto). We
can't seem to find any documentation referring to this problem. Wondering
if we can get support on this.
